Frost Action and Frost Heave - ACPA

WebFrost wedging is directly related to the fact that as water freezes its volume increases by roughly 9%. Liquid water percolates into existing cracks within a rock. The pressure of expanding ice causes cracks to widen and extend. This processes then repeates as melted water further fills newly formed cracks and freezes.
